Abstract
1. The selectivity of the C5-dehydrocyclization of n-heptane with the formation of 1,2-dimethylcyclopentanes and ethylcyclopentane was studied in the presence of Pt/C. 2. In the transition from a flow-type system to a pulsed system, the ratio of the yields of 1,2-dimethylcyclopentanes and ethylcyclopentane increases by an average of threefold. 3. The change found in the selectivity of C5-dehydrocyclization of n-heptane was explained from the standpoint of a sextet-doublet mechanism of this reaction and conformational concepts, considering the different density of coverage of the surface of the catalyst by the reagents.
